I found on my razor that an angle grinder did let me "get through the meat" faster, then cleaned up with files. However, now I have moved up to the Craftsman 2x42. I did the ceramic platen upgrade and the manual tracking upgrade and cut the table to get the belts out easier. It is A LOT less frustrating and a heck of a lot more productive than files. I'm glad I did a blade with files, but I love my little grinder. Maybe in a year I will go up to a GIB or similar, but for the money, my 2x42 seems to be going a long way.
Also, I will second the drill press. I use the crap out of mine. Cheap benchtop one from HF, but it works well. Get good bits though. I'm finding that out now. Cheap bits are a false economy.
